During an engine test on the ground, a propeller thrust $T=3220N$ is generated on the $1680-$kg airplane with mass center at $G.$ The main wheels at $B$ are locked and do not skid; the small tail wheel at A has no brake. Compute the percent change $n$ in the normal forces at A and $B$ compared with their "engine$-$off" values.

Answers:

$n_A=$

$\frac{?}{?}\%$

$n_B=$

$!\frac{?}{?}\%$
